Encoder Interface (Htl/Ttl/Ssi) - Siemens SIMOTION Equipment Manual

Interfaces

4.5 Encoder interface (HTL/TTL/SSI)

Connectable devices
The following devices can be connected to the PROFINET IO interface:
• PG/PC programming devices (communication with SIMOTION SCOUT / STEP 7)
• SIMATIC HMI devices
• SIMATIC controllers with PROFINET interface
• Distributed I/O
• Drive units with PROFINET IO interface (standard devices)
The SIMOTION D410‑2 DP/PN then assumes the role of a PROFINET IO controller and can offer the
following functions:
• PROFINET IO controller, I-device (also controller and device simultaneously)
• Supports real-time classes of PROFINET IO:
– RT (real-time)
– IRT (isochronous real-time)
The following functions are also supported by Industrial Ethernet:
• Communication between SIMOTION and SIMATIC NET OPC.
The "SIMATIC NET SOFTNET S7 (S7 OPC server)" software must be
installed on the PG/PC for this function.
• Communication with other devices over TCP/IP or UDP communication
• IT communication (e.g. via SIMOTION IT OPC XML‑DA)
• Communication based on OPC UA (Unified Architecture)
For further information on the software packages, see the SIMOTION PM 21 Catalog.
